[0033] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0034] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0035] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0036] The embodiment of the present utility model provides a floor scrubber body, such as Figure 1-5 As shown, comprise upper shell 110, driver 120, load mounting plate 130, cleaning tool 140, mounting block 150, mounting plate 160 and counterweight centrifugal block 170.Cleaning tool 140 is fixed on the load mounting plate 130.When load mounting plate 130 rotates, it drives cleaning tool 140 to rotate, and then can clean the ground.Upper shell 110 is positioned above load mounting plate 130.Driver 120 is fixed in upper shell 110.Upper shell 110 provides dustproof and protective effect to the parts of driver 120 and upper shell 110 inside.Mounting block 150 is connected to the output terminal of driver 120, and driver 120 is used to drive mounting block 150 to rotate.Mounting block 150 is rotationally connected with load mounting plate 130.Mounting plate 160 is fixedly connected to mounting block 150.Counterweight centrifugal block 170 is fixed on mounting plate 160. The rotation axes of the mounting block 150 and the load mounting plate 130 are eccentrically arranged relative to the axis of the driver 120 driving the mounting block 150 to rotate.

[0037] When the driver 120 drives the mounting block 150 to rotate, the load mounting plate 130 is driven to rotate accordingly, and the cleaning tool 140 on the load mounting plate 130 can clean the floor; at the same time, the mounting block 150 also drives the mounting plate 160 fixed with the counterweight centrifugal block 170 to rotate. The counterweight centrifugal block 170 provides centrifugal force, which can prevent the load mounting plate 130 from shaking easily, and the load mounting plate rotates more stably, thereby ensuring the cleaning effect of the floor scrubber.

[0038] In some embodiments, the floor scrubber body further includes a bearing 180, the inner ring of the bearing 180 is sleeved on the outer side of the mounting block 150, and the outer ring of the bearing 180 is connected to the load mounting plate 130. The mounting block 150 and the load mounting plate 130 are rotatably connected through the bearing 180, making the rotation of the load mounting plate 130 smoother.

[0039] Furthermore, load mounting plate 130 is provided with a receiving groove, to which a pressure ring 190 is fixed. Pressure ring 190 presses the outer ring of bearing 180 against the inner wall of the receiving groove, thereby clamping and securing bearing 180. This installation method facilitates the installation of bearing 180. Furthermore, the output end of mounting block 150 and / or driver 120 can pass through pressure ring 190 without affecting the connection between mounting block 150 and driver 120.

[0040] In some embodiments, the driver 120 includes a motor, and an output shaft of the motor is connected to the mounting block 150 to directly drive the mounting block 150 to rotate.

[0041] Furthermore, the mounting block 150 is provided with a mounting hole 151, and the output shaft of the motor is inserted into the mounting hole 151 to connect the output end of the driver 120 to the mounting block 150. The output shaft of the motor can be interference fit with the mounting hole 151 to be clamped and fixed in the mounting hole 151.

[0042] Furthermore, the mounting block 150 is cylindrical to facilitate the sleeve connection of the bearing 180. The rotational axis of the mounting block 150 and the load mounting plate 130 is coaxial with the central axis of the mounting block 150 itself. The mounting hole 151 is eccentrically arranged relative to the central axis of the mounting block 150 itself, thereby ensuring that the rotational axis of the mounting block 150 and the load mounting plate 130 is eccentrically arranged relative to the axis of the driver 120 that drives the mounting block 150 to rotate.

[0043] In some embodiments, the mounting plate 160 is provided with a through opening 161 , and the output shaft of the motor passes through the opening 161 , which can serve as a guide and limit for the rotation of the mounting plate 160 , so that the rotation of the mounting plate 160 remains stable.

[0044] In some embodiments, the mounting plate 160 is located above the mounting block 150, and a connecting hole 152 is provided on the top surface of the mounting block 150. A pin is passed through the mounting plate 160, and the pin is fixed in the connecting hole 152 to fix the mounting plate 160 and the mounting block 150 together through the pin.

[0045] In some embodiments, the cleaning tool 140 includes but is not limited to a cleaning pad, a brush and a cleaning cloth. The cleaning tool 140 can be fixed to the bottom and side of the load mounting plate 130, and the cleaning tool 140 can be detachably fixed to the load mounting plate 130 to facilitate replacement of different cleaning tools 140.

[0046] An embodiment of the present utility model provides a handheld floor scrubber, comprising a floor scrubber body according to any one of the above embodiments. The specific structure of the floor scrubber body can be referred to the above embodiments and will not be described in detail here.

[0047] In some embodiments, as Figure 6-10 As shown, the handheld floor scrubber of this embodiment further includes a handle assembly 200, a caster bracket 300, a caster 400 fixed to the caster bracket 300, and a fastening assembly 500. The handle assembly 200 includes a connecting bracket 210 and a support rod 220. The lower end of the support rod 220 is connected to the connecting bracket 210. The support rod 220 can be directly grasped by the user, or the support rod 220 is provided with a grippable component such as a handle or a protective cover, which the user can grasp.

[0048] The lower end of the connecting bracket 210 is connected to the upper housing 110, and the upper end of the connecting bracket 210 is rotatably connected to the caster bracket 300. This allows the angle between the connecting bracket 210 and the caster bracket 300 to be changed, and the angle of the support rod 220 to be changed accordingly. This adapts to the usage habits or height differences of different users, making it easier for users to use the floor scrubber of this embodiment. The fastening assembly 500 is provided on the connecting bracket 210 and the caster bracket 300 and is used to lock the connecting bracket 210 and the caster bracket 300 together or loosen the connecting bracket 210 and the caster bracket 300.

[0049] When it is necessary to adjust the angle between the connecting bracket 210 and the caster bracket 300, the connecting bracket 210 and the caster bracket 300 are loosened by the fastening assembly 500, so that the loose connecting bracket 210 and the caster bracket 300 can rotate relative to each other to change the angle; after adjusting to a suitable angle, the connecting bracket 210 and the caster bracket 300 are locked together by the fastening assembly 500, so that the loose connecting bracket 210 and the caster bracket 300 are difficult to rotate relative to each other, and the connecting bracket 210 and the caster bracket 300 can maintain the adjusted angle for stable use.

[0050] In some embodiments, the fastening assembly 500 includes a tensioning head 510, a screw and a limiting nut 520. The connecting bracket 210 and the caster bracket 300 are both provided with through holes 201 that are connected to each other. The screw is fixed on the tensioning head 510, and the screw passes through the through holes 201 of the connecting bracket 210 and the caster bracket 300. The limiting nut 520 is sleeved on the screw. The tensioning head 510 and the limiting nut 520 are respectively located on the side of the connecting bracket 210 and the caster bracket 300 that are away from each other. Specifically, the tensioning head 510 can be located on the side of the caster bracket 300 that is away from the connecting bracket 210, and the limiting nut 520 is located on the side of the connecting bracket 210 that is away from the caster bracket 300.

[0051] When the screw and the limiting nut 520 are tightened, the tensioning head 510 and the limiting nut 520 clamp the connecting bracket 210 and the caster bracket 300, thereby locking the connecting bracket 210 and the caster bracket 300 together. When the screw and the limiting nut 520 are loosened, the tensioning head 510 and the limiting nut 520 release the clamping of the connecting bracket 210 and the caster bracket 300. The tensioning head 510 not only clamps the connecting bracket 210 but also allows the user to manually hold the connecting bracket 210, thereby saving effort and facilitating operation when tightening the screw.

[0052] Furthermore, the fastening assembly 500 includes two toothed discs 530. Each toothed disc 530 is provided with a through-hole for a screw and / or a limit nut 520 to pass through. The screw can pass through the through-holes of both toothed discs 530, or the limit nut 520 can pass through the through-holes of both toothed discs 530, or the screw can pass through the through-hole of one toothed disc 530 and the limit nut 520 can pass through the through-hole of the other toothed disc 530. The two toothed discs 530 are respectively fixed to the connecting bracket 210 and the caster bracket 300, and the two toothed discs 530 are respectively located between the connecting bracket 210 and the caster bracket 300. When the connecting bracket 210 and the caster bracket 300 are locked together, the two toothed discs 530 engage with each other to further restrict relative rotation of the connecting bracket 210 and the caster bracket 300, thereby enhancing the locking effect of the connecting bracket 210 and the caster bracket 300.

[0053] In some embodiments, the through hole 201 of the connecting bracket 210 is a square hole, and the limiting nut 520 includes a square insert 521, which is inserted into the through hole 201 of the connecting bracket 210. When the whole machine is assembled, the installation process of the limiting nut 520 can be reduced. When the locking head 510 is screwed, the square insert 521 will not rotate with the locking head 510, and the locking head 510 can be screwed smoothly, which is convenient for operation. The limiting nut 520 is not easy to loosen from the connecting bracket 210.

[0054] In this embodiment, the square insert 521 can be integrally formed with other parts of the limiting nut 520 to facilitate manufacturing.

[0055] In some embodiments, the tensioning head 510 includes a rotating handle 511. The rotating handle 511 is larger in size and can provide a greater torque. The user holds the rotating handle 511 to rotate the tensioning head 510, which is more labor-saving to operate.

[0056] In some embodiments, the connecting bracket 210 includes a transverse arm 212 and two connecting arms 211, and the upper ends of the two connecting arms 211 are respectively connected to the two ends of the transverse arm 212, forming a U-shaped structure. The lower ends of the two connecting arms 211 are connected to the upper shell 110, and the lower end of the support rod 220 is connected to the transverse arm 212. The caster bracket 300 includes two support rods 310 and connecting rods 320 respectively connected to the two support rods 310, forming an "H"-shaped structure. Two casters 400 are provided, and the two casters 400 are respectively fixed to the lower ends of the two support rods 310, and the upper ends of the two support rods 310 are respectively rotatably connected to the two connecting arms 211. The fastening assembly 500 is arranged on the connecting arms 211 and the support rod 310 connected to each other. Since there are two groups of connecting arms 211 and the support rod 310 connected to each other, the fastening assembly 500 can be arranged on only one group of the connecting arms 211 and the support rod 310, or the fastening assembly 500 can be arranged on both groups of the connecting arms 211 and the support rod 310.

[0057] In this embodiment, two casters 400 are provided, which can more stably support the upper housing 110. Two corresponding support rods 310 and connecting arms 211 are provided to enhance the structural strength of the connection.

[0058] In some embodiments, the handle assembly 200 also includes a connecting base 230 and two handles 240. The connecting base 230 is connected to the upper end of the support rod 220, and the two handles 240 are respectively fixed on both sides of the connecting base 230. When in use, the user can hold the two handles 240 with both hands respectively, which is more comfortable to use and more convenient to operate.

[0059] In some embodiments, the lower end of the connecting bracket 210 may be rotatably connected to the upper shell 110 or may be fixedly connected to the upper shell 110 .

[0060] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
